JAR AND CLOSURE THEREFOR.

Specification of Letters Ifatent.

Patented Dec. 112, 1916.

Application filed January 27; 1913, Serial No. 744,457. Renewed December 9, 1915. Serial No. 66,020.

To all whom it may concern Be it known that I, GUsTAvn GLooKnn, a citizen of the United States, residing at WVashington, in the District of Columbia, have invented new and useful Improvements in Jars and Closures Therefor, of which the following is a specification.

The invention relates to a receptacle, and more particularly to the class of bottles or jars and closures therefor, and embodies various improvements over a patent granted to me February 21, 1911, entitled Jar and clo sure therefor, No. 984,808,

The primary object of the invention is the provision of a closure for bottles orjars in which the mouth of the latter may be hermetically sealed so as to provide a fluidtight juncture between the closure and the body of the bottle or jar, thus obvlating any possibility of the admission -ofair, dampness or liquid within such body, there by preserving the contents therein.

Another object of the invention is the provision of a jar and closure of the character described, in which rubber washers or gaskets of the ordinary resilient type may be employed, whereby, on the application of the cap or closure to the body of the ar, the said washer or gasket will be compressed between the same, thus effecting a fluid-tight closure at the mouth of the jar so as to prevent egress of the contents thereof or ingress of foreign matters therein.-

A still further object of the lnvention is the provision of a jar and closure therefor in i which the latter will be held against any possible lateral displacement when applled to the mouth of the jar and also will enable the sealing of such a jar for the preserving of the food or other substances contained therein. i

A still further object of the invention is the provision of a jar and closure therefor in which access may be easily had to the interior of the ar for the cleaning thereof to render the same sanitary, the closure being readily applied and removed from the jar at will and which, when applied, is designed to seal the said jar so as to make the same fluid-tight.

In the further disclosure of the invention reference is to be had to the accompanying Fig. 3 is a perspective view of the rubber gasket or washer; Fig. 4 is a view similar to Fig. 2, the washer or gasket being mounted thereon prior to its insertion in the ar; Fig. 5 is an enlarged fragmentary perspective view of the stopper body, showing the rela tive positions of the passage and the annular groove; Fig. 6 is a horizontal sectional view taken on the line 66 in Fig. 1.; Fig. 7 is a fragmentary perspective viewof the cover or stopper, showing a modified form thereof; and Fig. 8 IS a fragmentary vertical sectional view of the cover disclosed in Fig. 7.

Referring to the drawings, 5 designates the body of a jar or the like, preferably constructed of glass, although the same may be made fromany other suitable material, the cylindrical vertical wall of the jar being of uniform diameter throughout its length so that the jar may be readily cleaned and retained in a sanitary condition. The jar at its mouth has the inner edge 6 thereof beveled as shown, the purpose of which will be hereinafter more fully described.

Detachably fitted in the mouth of the body 5 is a closure comprising a stopper body? which is constructed from any suitable material, although preferably made from glass, the body -7 being reduced for substantially one-half of its depth to form a contracted rectangular portion 8 with respect to its remaining portion and also to provide a bearing shoulder 9, the latter being adapted to contact with the upper rounded edge 6 of the body of the ar when the cap or closure is inserted therein, thus limiting the insertion of the contracted portion 8 within the said body 5 of the jar.

The peripheral edge of the rim portion of the closure or stopper 7 is provided with a knurled or roughened surface 10, whereby thesaidclosure-or stopper may be gripped,

and the latter turned when inserting the same in the body of a jar or removing it .resp'ectively, spaced from each other, the

bearlng rib or surface 14: being of less diameter than the rib or bearing surface 13 so that when the closure or stopper 6 is inserted within the mouth of the body 5 of r the jar, the said bearing rib 13 will frictionally contact with the interior surface or wall of the said body so that there will not be any possibility of lateral displacement of the said closure or stopper when engaged in the latter.

Referring to Figs; 1 and 2 it will be seen that the stopper body 7 is provided with a passage 1 1 extending horizontally from the inner wall of the stopper body through the bearing rib 14 and terminates in an annular groove 14 formed in the said bearing rib.

The annular bearing surface or rib 13, when contacting with the inner surface of the body of the jar, will prevent the contents of the latter from leaking into the channel or groove 11 formed inthe said closure or stopper. Within the channel or groove 11 is seated the inner peripheral edge 15 of a resilient washer or gasket 16 so that on introducing the closure or stopper 7 within the mouth of the jar, the said washer or gasket 16 will be compressed between the annular bearing surface 14 and the body 5 of the jar, thus serving as a sealing medium between the closure and the jar. Should this washer or gasket 16 be compressed to an excessive degree upon inserting the closure or stopper in the jar its outer peripheral edge 17 will be squeezed into the channel or space provided by the beveled edge and which is provided to accommodate the same. The stopper or closure 7 the inner face of the contracted portion is provided with a centrally located recess 18 which is provided to give space for air that may exist within the body 5 of jar, and thus the airis forced out of the jar on the insertion of the closure or stopper within the mouth of the jar. However, this recess 18 may be dispensed with if deemed desirable. Now it, will be apparent that when the closure or stopper body is placed upon the mouth of the jar, air contained in the jar will pass outwardly through the passage 14? and thence distribute along the groove 14', so that as the stopper body is pressed downwardly a large quantity of the air passing into the groove by the gasket willbe pressed out of the groove immediately after the stopper body is arranged in position to diametrically seal the jar.

. Further pressure on the stopper body will result are; gasket being pressed upwardly to cover the passage 14k and the groove 14 and thus when the stopper has been pressed into final position on the jar, the jar will be hermetically sealed and rendered fluid-tight, thereby preserving the contents. By having the inner edge 6 of the jar beveled as mentioned heretofore sufiicient room is provided for the proper expansion of the gasket and although it is not necessary that the gasket fill up all of the space between the jar and closure, above the rib 13, when the stopper body is arranged in position on the jar, it will be apparent that when a large sized gasket is used all of this space will be taken up by the gasket, due to expansion thereof and which results when the stopper body is pressed downwardly into closed position on the jar. To remove the closure or stopper from the jar it is only necessary to insert a tool or other flat instrument between the rounded edge of the body of the jar and the rim portion of the closure or stopper and then by depressing the tool, the stopper or closure is lifted from the mouth of the ar.

In Figs. 7 and 8 I disclose a modified form of my device and in which it will be seen that in place of the passage 1 1 in the stopper body 7, I provide a vertical passage 14; extending from the peripheral groove 14 to the lower edge of the stopper body and which lower edge constitutes a bearing rib 13, it being further seen that the passage 14 extends transversely to and through the bearingribs13 and 1 1. Now referring to Fig. 8 it will be apparent that when the gasket 16 is supported between the bearing ribs 13 and 14 and reposes in the groove 11, as shown, the insertion of the stopper body 7 in the jar 5 will cause the air contained in the stopper body to pass upwardly through the passage 14 and between the stopper body'and the gasket, which, at the point of formation of the passage, will be sliglitly spaced from the inner wall forming the passage so that the air can readily pass upwardly through the passage and distribute itself along the annular groove 14: and it will be further apparent that when the stopperbody is pressed into final sealed position 115 on the jar, the gasket 16, engaged by the jar and bent upwardly, will entirely seal not only the annular groove 1 f but also the vertical passage 14.

It is thought that from the foregoing, the 120 construction and operation of the invention will be clearly understood, and a more extended explanation of the same has therefore been omitted.

Having thus described my invention, I 125 claim:

1. A cap or closure having an annular portion provided with an air passage, and a gasket held from movement in the annular portion and projecting into the passage in- 130 tel-mediate of the ends of the passage, whereby the passage is normally open above and below the gasket.

2. A cap or closure having an annular portion provided with an air passage, and a gasket mounted in the annular portion and projecting into the passage intermediate of the ends of the passage, whereby the passage is normally open above and below the gasket.

3. A cap or closure having an annular portion provided with a circumferential groove and an air passage intersecting said groove, and a gasket fitted in the groove and providing an air escape with the passage adjacent the supporting edge of the gasket.

4. A cap, or closure having an annular portion provided with a circumferential groove intersected by a passage, and a gasket fitted snugly in the roove and having its rear edge forming wlth the passage an a1r passage open above and below the gasket.

5. In combination, two interfitting members, a resilient gasket interposed between the members, one of said members having spaced annular grooves connected by a transverse passage, said gasket fitting in one of the grooves and extending across the passage, the said gasket being adapted to close the passage to the other groove when the members are interfitted.

In testimony whereof I affix my signature in presence of two witnesses.

GUSTAVE GLOCKER.
